Emerson35, previously responsible for his work on the PS3 Toolkit, has now released a new homebrew app. The app is called ES35's Customize v0.1 and it allows you to customize and clean up your RCO files. RCO files are XML files which control how your XMB behaves and looks.



Homebrew train is on its way.
BACKGROUND
RCOs are a bunch of xml files encrypted together,
you can mod these with RCOMage and make custom strings on your xmb.
RAFs are Video files. the only one that is a raf is coldboot.raf, which is the boot logo. Can be made with ColdBoot Maker. Tutorial Here.
AC3s are of course audio files, which is the boot sound.

I might make a tutorial on modding RCOs for noobs if i receive some positive feedback.
